ASH SFTER.

Application led January 5, 1925.

ifhis invention relates to improvements in ash sifters and lhas among its objects to improve the construction of such devices with a` view of providing a simpliied construction which shall afford a low manufacturing cost.

Another object of our invention resides in the provision of a dustless sitter which is completely enclosed and which permits the sifting of the ashes for separating the unburnt coal and cinders from the ash.

With these and other objects in view, our invention consists in the novel combination, construction and arrangement of the parts and members shown on the attached drawings, described in the following specifications and particularly pointed out in the appended claims.

Referring to the drawings, in which like reference characters denote like or corresponding parts, Fig. 1 is a longitudinal section through an ash si ter embodying our invention. Fig. 2, is a cross section of same, Fig. 3 is also a longitudinal section with the sifter in inverted position. Fig. 4 is a front or end view of the sifter showing the door construction.

Referring to the illustrations, 10 indicates the body of the sifter which is made from ay single piece of material 10A bent at the corners to provide a tubular casing or body of rectangular cross section. The material 10A may be joined together' with a butt `ioint as at 10B or with a lap joint.

The rear end of the casing 10 is closed with the end 10C which is flanged around its edges for riveted connection as shown.

The casing 10 is formed with longitudinal grooves 10D for support of the frame 11A of the screen 11, which grooves 10D are pressed outwardly from the inside of the casing.

The longitudinal screen 11 divides the interior of the casing into an ash can compartment 12 and the ash compartment 13.

rEhe front upper and lower edges 10E of the casing 10 are bent over the body to provide means for stiflening of these edges.

rllhe casing 10 is further provided with a pair of aligned integral extensions or ears 10F which afford a. support for the hinge rod 14 to which we. hingedly mount the doors 15 and 16 on the hinges 17'. A coiled spring 18 is wound around the rod 111 with its ends engaging the doors 15 and 16 for retaining them in normal closed position.

Serial No. 518.

'ihe doors 15 and 16 are cut out to provide clearance for the ears 10F, hinges 1? and spring' 18.

rlhe doors 15 and 16 are respectively formed with flanged edges 15A and 16A forproviding practically dust proof closures around the discharge edges of the casing.

1n operation, the ash pan 19 is placed with the ashes into the ash pan compar ment 12 by opening door 15 against the pressure of spring 18 which retains same in closed position, then the casing 10 is inverted into the position shown in Fig. 2, and bodily lifted and shaken until the ashes are thoroughly sifted through the screen 1l, after which sifting operation t-he door 16 is opened and the ashes are then scraped or dumped out of the ash compartment 13 whereupon the casing 10 is again reverted to the original position as shown in Fig. 1. rfhe ash pan is then withdrawn through door 15 with the unconsumed coal.

life claim:

1. An ash sifter embodying a casing comprising a tubular body of a single piece of material, a flanged end fixed within one end of said body for closing said end, a screen supported in said body extending longitudinally thereof, a pair of support-s on said body extending beyond the open end thereof, a hinge rod supported on said supports on the plane of said screen, and a pair of doors hingedly mounted on said rod for closing the ope-n end of said body.

2. An ash sifter embodying a casing coniprising a tubular body of rectangular cross section made of a single piece of material, flanged. end fixed within one end of said body for closing said end, a pair of loneiH tudinally ent-ending grooves formed wi opposed walls of said body, ay screen supported in said grooves, a pair of supports on said body extending beyond the open end thereof, a hinge rod supported on said supports on the plane of said screen., and a pair of doors hingedly mounted on said rod for closing the open end of said body.

A n ash sifter embodying a casing co1nprising a tubular body of rectangular cross section made of a single piece of material, a flanged end fired within one end of said body for closing said end, a pair of grooves extending longitudinally with opposed walls of said body, a screen supported in said groove-s, a pair of laterally aligned ears integral with said body extending beyond the open end thereof and on a plane With said screen, a hinge rod Supported in said ears, and a pair ol" doors hingedly mounted on said rod 'l'or closing the open end of said body.

eli. An ash sifer en'ibodyingl a casing Coinraising,` a tubular body or rectangular Cross section made of a single piece oi' n'iaerial` a flanged end fixed within one end or said body For closureT said end, a pair of grooves extending; longitudinally with opposed Walls of said body, a screen supported in said grooves, a pair of laterally aligned ears integral with said body enendinp; beyond the open end thereof and on aplane with said screen,` a binge rod suppored in said ears, and a pair of normally resiliently closed doors hingedly mounted on said rod for closing the open en d of said body.

5. An ash siftery embodying a Casing coinprising` a tubular body or rectangular cross section niade of a single piece of material, a anged end lixed Within one end of said body for closing said end, a pair of grooves extending' longitudinally with opposed walls olf said bod'yn a screen Supported in said grooves, a pair voli'vlateralluv aligned ears inregi-al with said body extending beyond the open eudhereof and on arplane with said screen, a hinge rod Supported in said ears. a pair of doors hingedlyniounted on Suid rod for closing' the open end of said body, and a` coil spring on said rod havingits ends in engagement with said doors for retaining' saine in closed position.
